Description
Description
Copying a subgraph at a specific block height would allow for an elegant alternative to rewinds when a divergence is identified in a subgraph.
Proposed workflow
1 - Identify divergence point N
2 - copy subgraph at block height N
3 - Allow graph-node to fully sync the copy
4 - Verify that the divervence is resolved
5 - use graphman copy activate to gracefully direct traffic to the corrected subgraph

Research direction
Start with the existing graphman copy activate entry point and trace how subgraph copies are represented and synchronized. Define how a copy at block height N is created, fully synced, verified, and activated without relying on a rewind; done means the proposed workflow works end to end.
